yeh but that just means the plug may not be wired up.but you should still be able to do a fault code test.

no i want to but my mate who has a valver is having his engine rebuilt now lol.
I think im decided on trying a new loom. Cant be my ecu as my car was perfeck before the build, only needed the starter motor replacing and there were no emissions issues/no bogging down at all etc etc.
if when the loom is replaced and it doesnt change, i'll just take it back to dave to look at as it must be something thats been done while putting the engine back in.

have you got a compression tester?do a test.was the hc's very high on the emissions test?.if its was your loom it would most likely show up on the fault code test.
